Specification of Letters Patent.

Patented July 30, 190'? Application filwl March 13,1907. 'Serial No. 362,931..

To all whom it may concert 1:

scription, such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to advertising devices, and has particular reference to improvements in such as partake of the character of postal letters or cards.

The object of my invention is to provide a combined circular. letter and envelop, in which a return postal another article or sample unify be inclosed and sent through the? mails.

My inventionconsists generally ina substantially rectangular, ungummed sheet of thick paper or card board-waving a letter or othercommunication printedupon' .it's inner face, said sheet being transversely scored upon two lines to form an intermediate portion and two end portions or flaps, and one of said portions beling provided with tongues or lugs formed from the body thereof, to'fold inwardly. and hold an inserted piece, card, or sample, suitable means being provided for gastening the sheet in iolded condition.

My invention, will be more readily und'eivetoed by reierence to the accompanying drawings, forming part or this specification, and in which sin-advertising device embodying my mvention,,th insert being shown in position therein, ready to be in'elcsed by the flaps or end portions of the sheet; and, Fig-file a perspective view of the device, folded and milled, ready [or the mails;

it's shown in the drawings, in carrying out my invention prefer t6 eihploy at substantially rectangular sheet of thick paper or card-board, The inner lace of 1135 sheet he'ansa commercial letter, or'other commu- E'igure 1, is a perspective view-of theinnerside of.

:nizntion, which is printed thereon. The sheet is upon two transverse lines, 2-2, which divide the sheet into an intermediiite portion, (,7, and two end flaps, or port ions, A and ii. The portion, A, is of substantially the so me width as the portion C, while the portion, ll, is usually narrower, the some being in tended to fold bet ween the other portions, as iudicat ed in Fig. 2. or the like, 4, to be iuclosed to the addressee, are placed upon one of the portions, prolerubly the intermediate portion, C. And this portion, C, as shown in the drawings, is cut at the ends to form two tabs, lugs, or tongues, 3, (which, being folded inwardly l'rom the dotted line positions of Fig. 1, securely hold the insert against end- One or more postal curds, pieces, siunples'.

wise motion on the sheet). To avoid sharp corners which might catc'li on other articles, I preferably round or bevel the edges of the sheet, 3, adjacent to the tabs. The insert having been placed and secured in this manner upon the flat sheet, the bottom {old or ilap, B, is first turned up over the same, and then the top told is folded down over them, and secured by .1. small gummedseal, or sticker, 5, (see Fig. 2). when the sheet is thus folded and scaled, it constitutes an en- 'velop. This envelop, however, is open at both ends and may be mailed as third class matter. lhe insert, being held by thefolds of the sheet, and by the tabs, 3, cannot escape from the open ends of the envelop.

Having thus described my invention, what I claim as new and desire to secure byLetters Patent is In a device of the class described, a folduble sheet of thick piper or card to bear a letter or communication upon its inner face and transversely scored to form upper and lower flaps to fold over the intermediate portion, and constitutinu'. when thus folded, an open ended envelop. tabs struck up from the body of the intermediate portion, within .the outline thereof and adapted to be folded over an inclosure to securely retain the same in said open ended envelop, substantially as described.

H In testimony whereof, I have hereunto set my hand, this 11th day of March,- lilo't, in the presence of two subscriblug witnesses.
